c Application filed December22, 1926. semi no, 15e,47c

This invention relatesto improvements in revoking mechanism for'weft replenishing looms, and it is the general object of the invention to provide a simple means forrpreventing the downward movement of a regularly moving transferrer arm should the shuttle be misplaoedon the transfer pick of the loom. (I

In looms. of the type set forth in patent to Ryon #l,372,316,-the transferrer is given a regular downward movement on alternate beats of the loom to present a weft detecting mechanism through the top of the shuttle box. When such a construction is employed on multi-eolor weft replenishinglooms, it is desirable not only to prevent transfer when the active shuttle is misplaced, but also to release the untransferred bobbin so as to avoid confusion of colors in the pattern. In my application, N o. 155,7fl1, I have shown a pair of actuators, one of which is operative under normal conditions to move the transferrer down while the loom is on front center and the other of which acts when the shuttle is improperly placed to bring the transferrer down at a later time in the cycle of the pick to ex pelthe untransferred bobbin while the lay is inits rear position. It is an important object of my present invention to avoid the use of a double actuator and substitute therefor a single actuator which may be disconnected from the transferrer arm by means of a shuttle feeler.

It is a further object of my present invention to provide bobbin supports for the mechanism which shall normally be in bobbin supporting position but one ofwhich is arranged to move to bobbinreleasing posi-. tion every timethe actuator is disconnected from the transferrer arm. v

It is a still further object of my' prese'n't invention to provide a 'yieldable' bobbin sup port and to give the same a bobbin releasing movement only at such times as the shuttle is misplaced.

With these and other objects which will appear as the description proceeds, my in; vention relates to the arrangements and combinations of parts hereinafter setrforth, and more particularly pointed out in the claims;

In the accompanying drawings, wherein a convenient embodiment of my invention is shown: v

F1gf6 15 a detailed horizontal section line 6-6 of Fig. 1. x i v I Referring to the dra'win s, 'I' have" pm vided' a frame, 10 on whic is mounted a multi-color weft replenishing mechanismlI having a't'ransferrer arm '12 pivoted thereto at 13. Vertically, reciprocating actuator rod 14 is given a downward motion-on each pick of the loom when the shuttle is under the weft replenishing magazine and normal'lf acts to movethe'trans'ferrer arm downwa d: lywheri the lay L is in forward position, This rodf14 is similar to the one set forth in the aforesaid patent to Ryon and has an upward movement immediately following its downward movement so a'sto carry the detector supported onthe'transferrer arm abovethe lay'before the lattermoves' to its rearposition. j i V 1 v My improvementsinclude a bobbins port 20 pivoted on a cross rod 21 on'tl te magazineand constrained toimo ve in a right hand direction about the'rod 21 by means'of atOrsion' spring 22 one'end of which engages fixed structure, as at 23 and the other end of which engages the 'support'asat set screw 25 in the supportengages' a'portion of the mec hanismframe to limit'move' ment of said support; A second support 26 forming no part of my present invention'andf being} of the usual form may beprovided for the other side of the bobbin.

secured a stud 28'on which is pivoted a' tripr 'Said trip has a finger 30 ex'tending' to v is a horizontal section on line the left as shown in Fig. 4 and has the oppo site side thereof connected to one end of a tension spring 31 the other end of which is secured to the support 20. The normal function of spring 31 is to hold the finger in position shown in Figs. 1 and 4 so that the end of the finger is below the stud 28.

Therod 14 is formed at the upper. end thereof with the head 40 having a pocket 41 which is normally occupied by a boss 42 rigid with the transferrer arm 12 said boss being preferably formed as part of a stud 43 secured to the transferrer arm. Theupper end of the head 40 has a notch defined by a vertical wall 44 and a horizontal wall 45 and positioned to cooperate with the finger 30 in a manner to be described hereinafter.

The transferrer arm is extended forwardly of its pivot 13 as at andhas a stud 51 normally lying in the bottom of a slot 52 formed in rod head 53 on the lower end of rod 54. Said rodis guided in a boss 55 fixed with respect 'to the magazine and a compression spring 56 interposed between the boss and head 53 tends to hold the rod in lower position. Said spring not only tends to'quicken an iupward movement of the transfer'rer arm after the'downward movement thereof so that the detector may clear the lay as set" forth in application to Chevrette-Serial N0. 16,7 49, but it also holds the transferrer in the position shown in Fig. 2 when the same is disconnected.

The devices to determine when rod 14 shall be disconnected from the transferrer arm include a shuttle feeler having a nose 60 positioned normally to be engaged by a misplaced shuttle, said nose being perforated as at 61' to have the rod 14 pass therethrough for free vertical reciprocation. The forw'ardly projecting shank 62 of the. feeler is guided in a'bearing member 63 and a compression spring 64 interposed between the nose 60'and the bearing 63 holds the shuttle feeler in rearward position normally with the head 40 of the rod in engagement with the lug 42.

, Under normal conditions the tip of a properly placed shuttle will be out of alignment with thenose 60 and the parts will remain ,in'the position shown in Fig. 1 when the layadvances. As the'lay nears its extreme forward position rod 14 will be given a quick downward motion by mechanism not shown herein butsimilar to that set forth insaid patentto Ryon. Immediately after the downward movement the rod will move upwardly and will be held by spring 64 so thatthe head 40 and more particularly the horizontal wall 45 will moveto one side of the fingerSO. The support 20 will therefore remain unmoved.

When the shuttle is misplaced, however,

it-willengage, thenose 60 as the lay'moves forwardly, compressing spring 64 and moving the rod 14 forwardly to cause pocket 41 to move out of registry with lug 42 as in Fig. 2. Head 40 thereupon engages finger 30 to move the same in a counterclockwise direction, but as spring 31 -is'weaker than spring 22 the support 20 will remain at rest to support the bobbin B intransfer position. The transferrer arm then falls until stud 51 is arrested by rod 54 and spring 56 and actuator rod 14-descends without the transferrer arm. During the downward movement ofthe rod 14 the end of linger 30 will move over the horizontal wall'45 to the position shown inFig. 4. As the rod 14 moves upwardly the finger 30 will be moved in a clockwise direction by the horizontal face 45 until engaged by the vertical wall 44. Be cause of the factthat thebottom of 'finger 30 is below stud 28, continued upward movewardly so that the nose60 will be disengaged from the shuttle, but this will not in-' terfere with the bobbin releasing movement of the support inasmuch as lug 42 holds head 40 in the position shown in F 4 during the upward movement of said rod 14. Dur-- ing the upward movement of rod 14 the pocket 41 will come to a position to'receive lug 42 and spring 64 will immediately move the'head 40to the left from the position shown inFig. 5 to that shown in F ig. 1. 5111" this way normal driving engagementofthe rod and transferrer arniis reestablished. From the foregoing it will be seen that I have provided means whereby a regularly moving transferrer arm 12 will be prevented from completing" its downward movement when a shuttle is misplaced. It will further be seen that means are provided for moving the bobbin support to release the bobbin when transferrer is revoked. It will fur-.

ther be seen that the bobbin support is given a releasing movement only at such times as the shuttle is misplaced. Also means. are provided for holding the transferrer arm in raised position when disconnected from rod 14 so that the untransferred bobbin will not be expelled from the magazine when thelay is in forward position. f I A Having thus described my invention it will be apparent that changes and modifications may be made thereinby those skilled in the art without departing-from the'spirit and scope of the invention and I do not wish-to disconnect the transferrer arm from the first named means to prevent said movement of the transferrer arm toward the shuttlewhen the shuttleis misplaced."
